Basic Introduction to Masscan

Masscan is really awesome. The main about Masscan that is different is it’s speed.

From the author - “ This is the fastest Internet port scanner. It can scan the entire Internet in under 6 minutes, transmitting 10 million packets per second.”

Masscan is really fast for a couple reasons:

  1. Custom TCP/IP network stack
  2. Packets are generated and sent asynchronously

Masscan is also very similiar to Nmap. It even has an –nmap switch to see what Nmap compatibility switches are available.

Run masscan --nmap to view what switches are similar across Nmap and Masscan
